If you're moving into a new home watch out for this dirty, but apparently legal, trick by SSE. If for some unaccountable reason the previous occupier opted for a business tariff you will automatically be assigned to a tariff which is not protected by the ofgem price cap. You won't know this, of course until two or three months down the line a huge bill thuds through your letter box. When you query the bill (after waiting hours for a telephone response) you are told the bill is correct and you need to change supplier. But you find you can't switch because your home is registered on the National Database as a commercial property ... and the only ones who can change this are your current supplier SSE. After another few weeks, during which time your bill is getting bigger and bigger, they will eventually change the database and you can switch supplier to great relief. My grandson was a victim of this scam and ended up paying more than 3 times the amount he should have paid as a price capped domestic customer. And it's no good taking this up with the Ombudsman Service as they just agree with their buddies in the industry and say they've done nothing wrong! Not all energy suppliers are greedy , exploitative vermin however. My grandson's electricity supplier, Corona Energy, acknowledged that he was a domestic customer and refunded the difference between their business tariff and the price capped domestic rate. So beware of SSE!! DO NOT USE THIS COMPANY.
